I&rsquo;ve uploaded a few different unfolded versions (some are minor variations on others) here:<br/>

Some are easier to &lsquo;fold&rsquo;, others may be desirable when the number of interconnects per pentagon should be minimal (2 max), others yet are highly anthropomorphizable (running chef?)<br/>
There&rsquo;s many more ways to unfold a dodecahedron, but these should get you well on your way.<br/>

It also makes sense.. why not charge a premium for a piece that really anybody could just cut themselves, many times over, from a $5 piece of double sided PCB?<br/>
Cutting hexagons and pentagons, the other hand, is surprisingly difficult unless you&rsquo;re good with a fretsaw/scroll saw / have your own router :)</p>111 on PRT-08847 - ProtoBoard - Penta-shape111urn:uuid:5e9dda4f-8594-7ff7-7c45-210d319fb5f92011-01-23T19:40:38-07:00<p>3D printed dodecahedron using these parts : <a href="http://www.thingiverse.com/thing:5750" rel="nofollow" >http://www.thingiverse.com/thing:5750</a><br/>

cmon, those are BIGGER</p>RDustinB on PRT-08847 - ProtoBoard - Penta-shapeRDustinBurn:uuid:2de0b5c6-505f-531d-a05a-387f6d56f5f72010-11-09T21:34:06-07:00<p>Hey SparkFun Gurus,<br/>
Is there any way you could start offering this same red-colored protoboard but that is a rectangle shape, so that one side is the same size as this pentagon and the triangle (4 holes by like 20 holes)?<br/>
Thanks!</p>Earlz on PRT-08847 - ProtoBoard - Penta-shapeEarlzurn:uuid:7fe4ff91-4628-26e4-5a30-f0137131d7922010-08-26T00:24:25-06:00<p>Why is this one so much cheaper than a plane 1" square piece of protoboard? I mean the 1" double sided square protoboard currently is $2.50 and this is 50 cents? that&rsquo;s a steal. I&rsquo;m definitely buying some of these instead, so what if the shape is weird.</p>BabeleDunnit on PRT-08847 - ProtoBoard - Penta-shapeBabeleDunniturn:uuid:b5a4f5ff-4e66-03da-5fc4-3beeae2d87752008-09-08T04:40:36-06:00<p>Ok. Now look at my homepage:<br/>

and PLEASE let us have also equilateral triangle ones! :) I BADLY need them!!! :)</p>
